ScienceDaily (2010-06-28) -- Researchers say this year's Gulf of Mexico "dead zone" is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery. The 2010 forecast, released by the U.S. National Oceanic and Atmospheric Administration (NOAA), calls for a Gulf dead zone of between 6,500 and 7,800 square miles, an area roughly the size of Lake Ontario.
